Multiband polarimetric imaging of HD 34700 with SCExAO/CHARIS

Minghan Chen, Kellon Lawson, Timothy D. Brandt +5

We present Subaru/SCExAO + CHARIS broadband (JHK) integral field spectroscopy of HD 34700 A in polarized light. CHARIS has the unique ability to obtain polarized integral field ima…

A Survey of Protoplanetary Disks Using the Keck/NIRC2 Vortex Coronagraph

Nicole L. Wallack, Jean-Baptiste Ruffio, Garreth Ruane +34

Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations of protoplanetary disks in the millimeter continuum have shown a variety of radial gaps, cavities, and spira…

Testing magnetospheric accretion as an H emission mechanism of embedded giant planets: The case study for the disk exhibiting meridional flow around HD 163296

Yasuhiro Hasegawa, Taichi Uyama, Jun Hashimoto +7

Recent high-sensitivity observations reveal that accreting giant planets embedded in their parental circumstellar disks can emit H at their final formation stages. While the ori…
